I got one also (from a different number in the list), and same thing - if
they really wanted to get in touch with me, they'd have left a message on
voicemail... ;)  If not, they get ignored unless I know the number...

My understanding of the scam was that you didn't get slugged the $50 until
you rang the second number (after being informed of the so called "win").

but I could be wrong...
